Restore Your Equinox’s Performance and Reliability
Is your 2010 or 2011 Chevrolet Equinox suffering from baffling engine issues like rough idling, stalling, poor fuel mileage, or a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance. A faulty ECM can disrupt everything from fuel injection to ignition timing, leaving you with an unreliable and inefficient vehicle. Don’t let a bad computer keep you off the road. This direct-fit, VIN-programmed Engine Control Module is the definitive solution to restore your vehicle’s factory performance.
Is Your Equinox Showing Signs of a Failing ECM?
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your ECM is the likely culprit:
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Unexplained drop in fuel economy.
- ✔ Engine misfires, hesitation, or stumbling during acceleration.
- ✔ Rough or erratic idling.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Intermittent or complete no-start conditions where the engine cranks but won’t fire.
- ✔ Loss of communication with the ECM when using a diagnostic scan tool.

Frequently Asked Questions
Do I need to do any additional programming after installation?
No dealership programming is required. The module arrives flashed to your VIN with the latest GM software. However, some vehicles may require a simple security relearn procedure (also known as a key relearn) to sync the module with your vehicle’s anti-theft system. This can typically be done in your driveway without any special tools.

After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct software and ensure perfect compatibility with your engine, transmission, and factory options.
